E-brake Lever Dash Mount - 1972 Dart

Can you replace the pin with a small grade 8 nut & bolt? Not many will sell just the pin unless they happen to have one to sell. I do have a complete set-up but don't want to part it out.
Understood but I just rebuilt mine and only need the pin. Is there a just a keeper washer on each side? Would you be able to measure the diameter of the pin? maybe I just get a small steel rod and cut it down to length and add the keeper washers on each end
